Question 4234Deck General70% to pass
A twin-screw vessel can clear the inboard propeller and maneuver off a pier best by holding a(n) _______________.
AI Explanation
The correct answer is A) forward spring line and going slow ahead on the outboard engine.
This is the correct answer because holding a forward spring line and going slow ahead on the outboard engine allows the twin-screw vessel to maneuver off the pier by pivoting around the forward spring line. This enables the vessel to clear the inboard propeller and safely move away from the pier. The other options would not provide the same level of control and maneuverability to safely clear the inboard propeller.
The other options are incorrect because:
B) Going slow ahead on both engines would not allow for the necessary pivot point provided by the forward spring line.
C) Going slow astern on the outboard engine would push the stern towards the pier, rather than moving the vessel away.
D) Going slow ahead on the inboard engine would not provide the necessary thrust to overcome the pivot point of the forward spring line.
